I cannot remember exactly :D but I have paid £124 inc a bag of 22kg from Leeds/Brad to El prat ,If I had pulled my finger out, it would have been £108 if i had booked a couple of days earlier >:(
Ryan air were around the £150 mark and that was with the 15 kg, granted these flight are from Leeds/Bradford not the cheepo airports"Stansted etc...." but LBA is less than a hour away and no car parking to add to cost.
By the way not much but got £1.30  back on Quidco  for booking with Jet 2, and also if it tracks 14% off the car hire price again using the Quidco site.
